An inner diameter of 2000mm vertical vibration cement pipe mold making
1. The outer mold
Vertical vibration cement pipe mold the outer mold by the cylinder of 4mm steel plate rolling machine rolling, welding school and an inner diameter into a Φ2360mm drums (outer diameter due to cement control after the Φ2360mm). Outer ring upper, middle and lower three, using the 6.5 channel numbers by coiling around the arc welding and school into a round hoop Φ2368mm inner diameter of the outer wall of the outer shell mold plate spot welding. Outer pole also with a No. 6.5 channel, welded between the outer ring, thus forming a solid skeleton.
After the completion of the work described above, the elliptical should be controlled within ± 2.5mm of. If ultra-poor, to be corrected with a manual jack, and then oxygen, acetylene flame baking outer ring about the site, if necessary, the amount of side edges school until school circle. Finally, oxygen, acetylene flame cut into two pieces of this semi-equal, and each welded into a mold shim Foreign boundary between the angle with 80 × 80. Φ22mm holes drilled on each of the four pairs of shim to irrigate when the outer mold fixed into a full circle with M20 bolts. After pouring cement pipe forming, loosen the bolt, the outer mold half, can release.
The upper end of the outer mold plane, uniform distribution of six sets of positioning screw (using T42 × 6 trapezoidal thread), nut welded to the outer wall of the ring plane, through the adjustment screw, you can precisely control the thickness by pouring cement pipes.

2. The internal model
Vertical vibration cement pipe mold die cylinder with a 5mm steel plate rolling machine rolling, welding and school into a calibrated outer diameter of the drum Φ2000mm (For ease from the module, which is slightly tapered cylinder, an outer diameter that is catchy Φ2010mm , under the port outer diameter Φ1990mm). The inner wall of the ring upper, middle and lower three, using 5 channel, after coiling around the arc, the weld joints and outer diameter respectively school Φ1900mm, Φ2000mm, Φ2010mm three round hoop, spot welded the inner wall of shuttering board. Between the inner ring welded to the inner wall of the pole (with a 5 channel) to form a strong skeleton. The inner wall of the oval should be controlled between ± 2mm, the same can be corrected with reference to the outer mold processes.
The inner mold plate of the upper casing, middle and lower ministries, have vertical and horizontal rod connected (with a 5-channel) and the inner wall of the annular phase soldering, the base vibration device will be straight beam welding rod in the center. When the job exciting force resulting through the rod, uniformly transmitted to all parts of the steel. After the mold is made, it should be lifted as a balance test, if the deviation can be welded with heavy rail in the inner wall of the roundabout. Thus, when the inner mold can remain vertical lifting motion, can reduce resistance from the mold, but also to avoid damage to the inner surface of the cement pipe.
3. The vibration device
By coupling two motor driven eccentric (eccentricity e = 23mm respectively for Φ2m steel; e = 18mm for Φ1.5m steel) rotates, generating exciting force concrete tap. Production and installation of the eccentric, must be in strict accordance with design requirements, otherwise vibrating force generated by eccentric unevenness affects the quality of concrete pipes, cement pipes and even destroy the structure of the mold itself and personal safety.

Vibration welding device is a vertical center of the inner mold, both ends of the spindle is equipped with four bearings, housings or with steel forgings, mold in order to avoid due to the intense vibrations caused by broken parts. Bearing bolted to the base beams.
After assembly, pull couplings, cam should rotate freely, if the resistance, indicating the motor shaft and shaft misalignment, loosen the fixing bolt bearing and motor through shims to adjust.
Cement pipe mold during use, should always check and found that the phenomenon should be added to weld cracking.
